| Description
| - The increase of chlorophyll fluorescence yield in chloroplasts in a 12.5 Hz train of saturating single turnover flashes and the kinetics of fluorescence yield decay after the last flash have been analyzed. The approximate twofold increase in F-m relative to F-o, reached after 30-40 flashes, is associated with a proportional change in the slow (1-20 s) component of the multiphasic decay. This component reflects the accumulation of a sizeable fraction Of Q(B)-nonreducing centers. It is hypothesized that the generation of these centers occurs in association with proton transport across the thylakoid membrane. The data are quantitatively consistent with a model in which the fluorescence quenching of Q(B)-nonreducing centers is reversibly released after second excitation and electron trapping on the acceptor side of Photosystem II.

- Práce se zabývá analýzou kinetiky nárůstu fluorescenčního výtěžku během serie saturujících záblesků a kinetikou dohasínání fluorescence. Dokazuje, že nárůst fluorescence souvisí s nárůstem amlpitudy pomalé složky dohasínání fluorescence, která odráží akumulaci části center fotosystému II, které nemohou redukovat akceptor Qb. Ukazujeme, že koncentrace těchto center souvisí s přenosem protonů přes membránu (cs)
